I wrote a hack that overrides IO.read.  When IO grabs the file, it 
checks the file extension;  if it's an erb template, it replaces <? ?> 
(with some variants) markup with <% %> before passing along the content.

It was a Good Enough sort of thing for the circumstances.


class IO
   class <<self
     alias real_read read
   end

   def IO.read( *args )
     return IO.real_read( *args ) unless args[0].to_s =~ /\.rhtml/i
     text = IO.real_read( *args )
     s = ''
     text.each_line(  ) { |l|
       next if l =~ /<?xml/
      l.gsub!( '<?eq', '<%=')
      l.gsub!( '<? ', '<% ')
      l.gsub!( '?>', '%>')
      s << "#{l}\n"
     }
     s
   end
end
